When constructing partition walls made of plasterboard, both on the grate of sheet metal profiles and wooden square timber, it is important to very accurately fix the bottom profile under the top profile..

We drop him in three places – mark points at the walls and in the middle of the length and on the ground, according to which we will place the bottom profile and fix it with anchors.
